Next: Lettuce Based Self Growing Electric Wires

Scientists may be able to use lettuce to create 'self-growing' electricity wires in the future, paving the way for biological computers and 'bio-robots'.

Andrew Adamatzky from the University of West England conducted a series of tests with lettuce seedlings. To create bio-wires, he bridged two electrodes made from aluminum foil with a seedling placed onto the electrodes in drops of water.

He applied electrical potential between electrodes ranging from 2 to 12 volts, and calculated the seedling's potential transfer function that shows output potential as a fraction of input potential — amount of energy produced relative to energy put in.

He found that resistance of the seedling repetitively changed or oscillated. He found that the output potential was 1.5-2 V less than the input potential, "so by applying 12 V potential we get 10 V output potential", he said.

While admitting that this meant wastage of energy, he said the problem could be tackled once methods are developed for reliable routing of plant roots between living and silicon components.
